Thanks Yves.
Sorry, I haven't had the time to get into the voiD details, but it is certainly the case that we have a lot of linksets that are independent of the KBs; in fact, that is our primary linkage mechanism.
So if voiD has a problem with that, then there may be a problem.
(In fact years of hypertext research suggest that embedding links is not the best way forward, and using linkbases is the best way to go, but that is another thread if anyone wants to pick it up.)
The CRSes are not Linked Data at the moment, but will be I'm sure (again, time permitting).
As an example, the dblp.rkbexplorer.com CRS for Tim is at:
Which you can see at the top of his page on that site:
And if you want to see all about him across all the CRSes and KBs in *.rkbexplorer.com, you can try
This also shows a picture of the linkage.
(And yes, it does show his dbpedia stuff by automagic linkage.)

So one day soon we will need to be able to describe such things.
And if anyone wants to tell me what I should publish using voiD I will be very happy :-)

I think the CRS system proposed by Hugh and Afraz at the last LDOW is
publishing linksets independently? Hugh, would be Void expressible
enough to encompass what you publish?
Although there is still the possibility to consider it as an
independent dataset, having two linksets pointing to the two datasets
being interlinked.
